LGF,
Just some thoughts on the basics for you to understand:
1. The drawing represents the part you wish to machine in CAD. It can be 2d or 3d. The 3d has all the information about the part.
Width, length, height for every feature.The 2d does not, ie; a plan view has no height info.
Machining considerations are taken into account even at the drawing stages.
2. The CAD output will be used by CAM and the output must be appropriate for the CAM software that will be used.
All CAM software is similar but vary in capability, but, in general no software is "smart" enough to know how you want to machine
the piece, which includes but is not limited to, where the piece is located, what tooling will be used,the machining steps that
will be done, etc.
3. Matters not what CAM you use you will need to define the machining in some way to the software. Once that is done,
the software will produce the code to machine it to a controlling software, ie MACH. The code must be of the proper format
that the controller understands, so a specific proccesor is used.
The above understood, you need to create a correct drawing to represent the part in CAD, save / export that info for use by CAM adding additional info as required to machine it and have the CAM generate the code in the proper format to MACH.
So simplisticaly it requires an understanding of CAD, CAM, and machining practices.
One must read / study the manuals.
There is a manual for LazyCam in members Doc's, there is a manual and videos for Cambam on their site.
Have fun,
RICH
